A projectile can have the same range R for two angles of projection. If T 1 ​ and T 2 ​ be the time of flights in the two cases, then the product of the two time of flights is directly proportional to

Range is same for complimentary angles. T 1 ​ = g 2 u s i n θ ​ and T 2 ​ = g 2 u s i n ( 90 − θ ) ​ and R = g u 2 s i n 2 θ ​ ∴ T 1 ​ T 2 ​ = g 2 u sin θ ​ × g 2 u cos θ ​ = g 2 R ​ .
